In the past, the important factors of buying the sports shoes for the customers were price and comfort. However these days, the sports shoes are considered as a part of fashion and may not satisfy the customers because their emotional preference have not been properly considered in design phase. The customers' desire and expectation for unique design are growing. Thus, the development of sports shoes not only considering the anthropometric foot characteristics but also satisfying the customers emotional preference is needed. In this study, the basic data on the customer's emotional preference to the design of sports shoes were obtained using human sensibility ergonomics approach and formed a data base. Also, we developed ail interface that can be used for the customers to select the emotionally preferred sports shoes.

Any place where exercise is common, such as a club, sports hall, or school, is considered a place for teaching sports. When doing sports, a very safe environment for sports should be chosen. The athlete should consider the safety of sports facilities and equipment, and if there is a defect, he should refrain from exercising in these places. The safety of sports facilities is very effective in creating people's sports activities, with the benefits of staying away from physical harm, enjoying sports, and having mental peace. Everyone has the right to participate in sports and recreation and to ensure that they enjoy a safe environment. The ability to manage and solve issues that may arise plays the most critical role in creating a safe environment. The quality of construction materials used for the construction of sports facilities is of great importance. In this work, the resistance and water repellency of concrete constituents for the construction of sports buildings have been investigated by nanoscience. Nano-concrete material solves the main problem of concrete surfaces, i.e., the entry of water and humidity into the structure. It also gives it a self-cleaning ability with its water repellency. Nanoparticles are placed between pores and cover the cracks, which causes roughness in the surface structure of concrete. The high roughness of the surface of the coated concrete caused its super-hydrophobicity. In hydrophobic surfaces, the higher the contact angle, the more hydrophobic the surface will be. In order to investigate the hydrophobic properties, silica nanoparticles, silica nanoparticles, and fly ash were prepared on concrete, and their properties were analyzed.
